# C1 graph transformations watch

1. Hi I just wanted to clarify if I needed to work out the value of k in question 2b or just draw the graph shifting up by a value of k? Thanks for any help in advance
2. The second one
3. You would just need to make the correct change to the graph, showing where it crosses the axis
It's saying, in any situation where you add a number at the end of the equation, what happens?

Oh right that makes sense, okay thanks

6. There is no way you could work out a value for k in this question. It doesn't give you any more information so you just have to think about where the graph would cross the y-axis, since it does not cross the x-axis as k is a positive constant. You can just think about this graphically or you could work out the value for the discriminant in terms of k - which will show you that the discriminant is always less than 0 (as k is positive). So in this question all you are doing is finding the y intercept in terms of k - when x=0
